Patent GB-749833-A (GB)
Title: Method of and apparatus for indicating, or actuating a control device in consequence of, a breakage in materials of low electrical conductivity such as textiles
IPC: D01H13/16
Filed: 1953-02-27
Abstract: 749,833. Signals and stop-motions in textile spinning &c. machines. BREUNING, E. Feb. 27, 1953 [Oct. 17, 1952], No. 5589/53. Classes 120 (2) and 120 (3). In a method of indicating or actuating a control device, e.g. an automatic stop-motion, consequent on breakage of a thread or roving during a textile process, e.g. spinning yarns, the broken material contacts and thereby modifies the electric potential of a testing electrode which acts in conjunction with a charged electrode on an indicating and/or control means to which it is connected; the testing electrode is not connected to earth and normally has no voltage applied thereto. As shown in Fig. 1, the pipe-line 1 of a thread suction device houses a charged electrode 2 and a testing electrode 3 which is connected to the grid of a thermionic valve 4; when a broken end contacts the electrodes 2 and 3 the potential of the latter and hence of the grid is altered so that, given suitable adjustment of the grid bias by means of a resistance 5, the anode current of the valve 4 is varied, and such variation may be used to initiate operation of a stop-motion. The electrodes may be constructed as rakes, Fig. 2 (not shown), which make operating, albeit momentary, contact with all pieces of broken material passing through the pipe. In the arrangement of Fig. 3, an alternating voltage from a transformer 6 is applied to the electrode 2, and the electrode 3 is connected to the high resistance control input of an alternating current amplifier; the electrodes are surrounded by earthed protective rings 11 and 12 of conducting material, and the effects of inadequate insulation or capacitance therebetween are reduced by a condenser 9; a rectifier 13, with signalling and controlling devices 14 and 15, is connected to the output of the amplifier 10 and controls a stop-motion (not shown). The embodiment of Fig. 4 comprises a double triode 16 with one cathode, one triode system operating as a rectifier while the other determines the magnitude of a compensating current for a polarized relay 17; a normal balance of anode currents is upset when the potential of the grid of the rectifier system changes (as a result of the breakage, as before), and the relay acting through a relay 18, operates a signal and control device to release another relay which arrests the drive for the thread or roving, through an auxiliary contact 19 of relay 18, the anode current of the second triode system is reduced, the armature of the relay 17 therefore reverses after an adjustable predetermined time interval and resets the circuit arrangement so that the drive may continue. A single apparatus as described may be connected to several input stages of a textile machine.

The arrangement is such that the handle 13 remains in the ON position when the circuitbreaker trips but an extension 45 of the arm 30 is visible through aperture 46 of the cover to indicate the tripped condition. Handle 13 rotates a hexagonal spindle 14 to which a plate 23 carrying a pin 38 is keyed. The pin 38 engages in a shaped slot 39, 41, 42, Fig. 6, of the arm 30 which is pivoted at 32. On closure of the switch by handle 13 plate 23 and pin 38 move clockwise from the OFF position to the intermediate position (shown, Fig. 6). The pin 38 initially in recess 41 of arm 30 positively moves the arm 30 but as pin 38 passes lobe 40 the arm 30 is free to move clockwise as the circuit breaker actuator 11 snaps to the ON position. Recess 42 of the arm 30 also permits return movement of the arm 30 relative to pin 38 when the circuit breaker 10 is tripped. Snap-action motion is also provided for the handle 13 and comprises a compression spring plunger system (not shown), coupled to the plate 23 at slot 24 and moving over a dead-centre position;

Title: Improvements relating to photographic apparatus
IPC: G03B17/52
Filed: 1967-02-08
Abstract: 1,149,530. Photographic apparatus. INTERNATIONAL POLAROID CORP. Feb. 8, 1967 [Feb.11, 1966], No. 6088 / 67. Heading G2A. A self processing photographic camera of the kind containing a supply of a photo-sensitive image recording sheet 34 and a coil of an image receiving sheet 36 which sheets are extracted from the camera after passing between pressure applying rollers 38, 40, is provided with means for arresting the sheets when a length corresponding to one exposure has been extracted, and with means for severing such a length from the remainder of the sheets in the camera. The arresting means comprises a disc 50, having two projections 52, mounted co-axially with, but rotatable independently of, the roller 38. As the sheets are extracted, the disc 50 rotates by frictional coupling with the roller 38 until one of a series of marginal openings 64 of the sheet 36 is engaged by a projection 52, which projection then punches a hole in the corresponding position of sheet 34. The disc continues to rotate until the other projection engages the free end section 108 Fig. 3, of a first arresting member 104, which section is deflected against a support member 104, to arrest rotation of the disc. The sheets are then severed on the edge 90 of a cutter bar 88. Depression of a button 102 causes the bar 88 to move inwardly (forwardly) from its operative position, thereby moving the member 104 lengthwise so that a notch 110 thereof is aligned with the projection 52, thus allowing the section 108 to return to its undeformed position. The member 104 returns to its initial position when the sheet severing member is released. To prevent the arresting mechanism being rendered inoperative if the bar 88 is retained by the operator, so that the notch 110 remains aligned with the projections 52, a second arresting member 112 formed of a resilient strip material is provided mounted on the member 104 for limited length-wise relative sliding movement therebetween. Means are also provided to allow of the member 88 returning to its initial position in the event of a projection 52 being engaged within the notch 110 and/or against the side of end section 118 of the member 112.

Abstract: 816,449. Fuel injection pumps. C. A. V. Ltd. Feb. 24, 1958 [Feb. 25, 1957], No. 6190/57. Class 102(1). [Also in Group XXVI] In a liquid fuel supply system for an internal combustion engine in which an engine-driven injection pump a is supplied with fuel from a supply tank g by a feed pump e, means are provided responsive to a fall in pressure of the fuel supplied by the feed pump for moving the injection pump control member b to the zerodelivery position and thus stopping the engine. The feed pump is driven by an electric motor f controlled by a switch h and delivers fuel through a pipe o to the injection pump and to a cylinder i having a diaphragm or piston k arranged to act as a spring-loaded lever m. In normal operation the pressure of the fuel in the pipe o acts on the piston k to keep the lever m in an inoperative position, the injection pump then being controlled by the normal governor c or by a manually operable lever d. If the tank g empties whilst the engine is running, the consequent fall in pressure in the pipe o allows the lever m to be moved by the spring n to move the member b to the position at which the injection pump ceases to deliver fuel, the engine thereby being stopped and the risk of drawing air into the system avoided.
